I need to validate the user input of a JSpinner, and if invalid, I need to undo (rollback) the value change. What is the best way to do it?

A:
Well, if you save the old value from the last time you validated the input, you can then reset the value of the spinner back to the last valid value.
boolean valid = validate(spinner);
if (valid)
validValue = spinner.getValue();
else
spinner.setValue(validValue);
Maybe something like that.

I hoped to see something more... original.

Oh, sorry. I wouldn't bother thinking of a more imaginative way of doing it. THis works and is fairly quick.
